Address Validation Best Practices: Reduce Failed Deliveries and Returns

The Cost of Bad Addresses

Address issues cause 5-10% of all delivery failures. Each failed delivery costs $15-$25 in reshipping, customer service, and lost goodwill. Proactive address validation prevents most issues.

At Checkout (Recommended)

Post-Order (Backup)

API Integration

Validation Request

const validateAddress = async (address) => {
  const response = await fetch('/api/address/validate', {
    method: 'POST',
    body: JSON.stringify({
      street1: address.street1,
      street2: address.street2,
      city: address.city,
      state: address.state,
      zip: address.zip,
      country: address.country
    })
  });
  return response.json();
};

Response Handling

const handleValidationResult = (result) => {
  if (result.valid) {
    // Use corrected address
    return {
      status: 'valid',
      address: result.corrected_address,
      changes: result.corrections
    };
  }
  if (result.suggestions.length > 0) {
    // Offer suggestions to user
    return {
      status: 'suggestions',
      options: result.suggestions
    };
  }
  // Address invalid
  return {
    status: 'invalid',
    errors: result.errors
  };
};

Autocomplete Implementation

User Experience Flow

Frontend Implementation

const AddressAutocomplete = () => {
  const [suggestions, setSuggestions] = useState([]);
  const handleInput = async (value) => {
    if (value.length >= 3) {
      const results = await fetchAddressSuggestions(value);
      setSuggestions(results);
    }
  };
  const handleSelect = (suggestion) => {
    // Populate all address fields
    setAddress({
      street1: suggestion.street,
      city: suggestion.city,
      state: suggestion.state,
      zip: suggestion.zip
    });
    setSuggestions([]);
  };
  return (
    

       handleInput(e.target.value)}
        placeholder="Start typing address..."
      />
      {suggestions.length > 0 && (
        

          {suggestions.map(s => (
            
 handleSelect(s)}>
              {s.formatted}
            
          ))}
        
      )}
    
  );
};
